Keaton was “born to voice Ken,” joked Unkrich, pictured, adding that it was the doll’s big-screen debut.

Pixar screened a scene from “Toy Story 3” in 3-D — the third movie concerns what happens to the toys when their owner, a now-grown Andy, leaves for college — as well as some “old reel footage” introducing groovy new cast member Ken.

We see Ken’s Dream House, where things are hunky-dory — Ken shows off his shades and well-sculpted chest while being interviewed about the glamorous life.

When asked about being “a Barbie accessory” and a “boy toy for girls,” however, the offended Ken removes his microphone and cuts the interview off. “Toy Story 3” comes out in 2010.
